commit 63165a94862c2b338e329cbd781712c7a7a1b475
Author: Efraim Flashner <efraim@flashner.co.il>
AuthorDate: Wed Mar 6 09:09:56 2024 +0200

    cpu: Be consistent with x86_64 micro-architecture names.
    
    * gnu/packages/golang.scm (%go-1.18-x86_64-micro-architectures): Rename
    micro-architectures from x86_64-v* to x86-64-v*.
    * guix/cpu.scm (cpu->gcc-architecture): Return x86-64 as the fallback.
    (cpu->micro-architecture-level): Rename micro-architectures from
    x86_64-v* to x86-64-v*.
    (gcc-architecture->micro-architecture-level): Same.
